Hi, I have a few data validation questions which I'm struggling with.
Firstly I am trying to make a bookings form, so am looking for a dropdown with every fifteen minutes between open and close. Now, Time as a data validation does not provide a drop down, so I am doing it based on a list of available times. Because a) our opening times vary across the week, and b) my dynamic list of times will exclude fully booked periods, I need the source of the list to vary in length to avoid a load of blanks. Basically - what the "ignore blanks" tick box is ASSUMED to do, before you quickly learn it doesn't. What is the work around to achieve this? I have tried googling and have copy and pasted a load of different options but once I've edited them from row to column and the example cells to mine etc, I just don't get the results.
Secondly, I am entering a box for the customer to enter an email address. I am still reading up on excel sending emails, but I want to ensure they type in a correct email address, i.e. to not allow them to submit without at least it having an @ sign in it! Again data validation: does contain an @ sign, and maybe a . Is this possible?
Thanks in advance for all your help,
